Area residents are invited to clean out their old papers and unwanted personal documents at a free shredding event in Knoxville this weekend. McKay Insurance has hired a Shred It mobile truck to help the community safely dispose of sensitive documents such as bank statements and tax records in an effort to help prevent identity theft. Attendees are asked to stay with their box until it is processed for safety reasons. The event will take place Saturday from 8am until noon and is free and open to the public.
